Description

technical field [0001] The invention relates to the field of fuel cell vehicle power system test bench control, in particular to a fuel cell vehicle power assembly integrated test system. Background technique [0002] Fuel cell vehicles are regarded as an important research and development direction for the sustainable development of the new energy vehicle industry due to their advantages of zero emission, high efficiency, clean fuel and renewable energy. At present, in the development process of existing fuel cell vehicles at home and abroad, there are limited test equipment resources for comprehensively considering the adaptability of the vehicle environment (including climate, etc.), the adaptability of road driving conditions, the durability and reliability of the power system, and the comprehensive performance of the vehicle. , and the cost of testing is expensive, and correspondingly, testing specifications and standards are relatively scarce. [0003] Therefore, acco...
